I'm getting a raft of errors when I try and compile the space invader code. It appears it's trying to call things that are undeclared - but to be honest I can't make head nor tail of it. I think I've got all the libraries installed.Note communication with the GEMMA is fine and I've successfully uploaded Blink. At this stage I'm just trying to compile the code. anim.h is present and appears correct as well.Running Ardunio 1.8.1 on OSX El Capitan.
